From the reddit AMA today with Lisa Su (CEO): 7th) Will all Zen products have all of the instruction sets and platform extensions, or could lower end chips lose features like virtualization? A7: In the consumer client space we have no plans to turn off virtualization or features. 9th) Does AM4 / consumer ZEN support ECC memory? A9: ECC is enabled on Ryzen and AM4. [ https://www.reddit.com/r/Amd/comments/5x4hxu/we_are…

my homelab is ready.

Really not wanting to poop on anyone's parade but an off lease Dell/HP/Lenovo workstation used from eBay will beat the pants off anything else for homelab. You can get an E3-1240 V2 with 8Gb RAM for the kingly sum of ... $200. Including motherboard, chassis and PSU.

Earlier quoted context omitted.

Several people contacted ASRock in the last few days. And the reply always was that ECC is fully supported, e.g. https://news.ycombinator.com/item?id=13762950

That's good information but still doesn't tell us that these cpus support ECC, right? Maybe the motherboard fully supports ECC when used with a future 1800X-PRO but not with the 3 chips reviewed here. In that case anandtech saying "We know that it is disabled for the consumer parts" and ASRock saying "ASRock AM4 motherboards fully support ECC function" can both be true.

Gigabyte mobos say you can use ecc memory but not run them in ecc mode. "Support for ECC Un-buffered DIMM 1Rx8/2Rx8 memory modules (operate in non-ECC mode)"

And you're also stuck with a $200/month power bill and the full home heater....

Don't get me wrong, I have a bunch of rack pull servers and they're great for the price but I colo mine for less/server than the power bill/server would be at home and have them ona faster connection. I stick with low power options for light in-home usage

The single-socket Xeon E3 that GP mentioned is 69W TDP. The Ryzen 1700 is 65W, while the 1700x and 1800x are 95W. Why do you think the Ryzen box will be a lot less power hungry?

Wow. AMD has really pulled through on this one. They are really giving Intel a run for their money. This is going to be great for consumers. What is interesting is the HUGE jump in multi-threaded performance on AMD. Very interesting.

But it's still losing in every web and office single threaded benchmark. EDIT: compared to 7700k that costs about the same

I think people run enough browser tabs (+ their office suite + background OS tasks) where the core difference will outshine the single-core speed. It's not hard to overwhelm 4 real cores.

The Ryzen 1700 has 8/16 and much better performance compared to the mentioned Xeon E3. I think the Ryzen 5's would be the ones to look out for (still more cores and much less price), hope they push the power consumption even lower.

Ryzen 7 chips focus on heavily multithreaded work. When you are dealing with every day apps and games you are more concerned with IPC (instructions per cycle) and I'm sure we'll see better performance in that arena with Ryzen 3 and 5
